关键词： Breast   Cancer   RFID   Tag localisation   Wire-guided local excision   Wire-guided localisation  

摘要： Background: Breast cancer screening programs have increased the detection of nonpalpable breast lesions. Given its accuracy and low failure rate, wire-guided localisation has long been the gold-standard prior to breast conserving surgery (BCS). Recently, several non-invasive localisation modalities have been developed, with varied efficacy reported. This study aimed to evaluate tag localisation's impact on margin positivity and re-excision rates and utility in management of benign lesions compared to wire-guided localisation. Methods: A retrospective comparative study was performed of patients, who underwent wide local excision (WLE) from 2020 to 2023, in a single institution. Descriptive statistics were performed on patient, tumour and radiological findings. Binary regression analysis was used to assess the association between localisation techniques and margin positivity and re-excision rates. Results: Of 680 patients included, 123 (18.1 %) underwent tag localisation, 298 (43.8 %) underwent ultrasound (US) guided wire localisation and 259 (38.1 %) underwent mammogram (MG) guided wire localisation. Tag localisation was associated with a significantly lower rate of positive margins compared to wire guided localisation (p < 0.03). While not statistically significant, a trend towards lower re-excision rates was observed post tag localisation (11.24 %) compared to both US guided wire localisation (18.99 %) and MG guided wire localisation (20.66 %). However, tag localisation was significantly more likely to fail and require a subsequent wire (0 = 0.0003). Conclusion: While associated with fewer positive margins, tag localisation did not significantly lower re-excision rates and was more likely to fail than wire-guided localisation. Further studies may elucidate its possible benefits in select patients. © 2025 The Authors

摘要： The entry of potential competitors disrupts the original market equilibrium, which in turn hinders the adoption of RFID technology. This paper focuses on a supply chain consisting of one supplier and two retailers in a master-slave relationship. It develops a decision model for RFID investment, employing a simultaneous game to analyze how RFID technology influences the revenue and strategic behavior of supply chain members. Based on numerical analysis, the key findings of this study are as follows: (1) The adoption of RFID technology increases the revenue of both retailers to some extent. (2) The incumbent retailer demonstrates a stronger ability to withstand risks. (3) The maximum label cost and revenue-sharing rate that suppliers can bear are influenced by the market equilibrium in the absence of RFID. This study offers both theoretical and practical insights for promoting RFID technology in competitive markets. © 2025 IGI Global. All rights reserved.

摘要： This work presents a novel methodology of an RFID system for peer-to-peer surveillance of products in warehouses. The methodology also uses a novel antenna sensor that continuously senses the tags/ products within its radiating field region. This designed antenna sensor works in a dual frequency range of 865-867 MHz and 902-928 MHz with a peak gain and typical VSWR of 3.9 dBi and 1.05 respectively. To demonstrate the proof of concept of the methodology, 4-identical antennas are fabricated and stacked on the racks where the products along with tags are used to be placed. These tags are being monitored by the server that compares the ordered products with the collected products from the shelves and raises the warning or an alarm when any unwanted tags is moved or missing from the locations on the shelves. Multiple measurements are performed to check the accuracy and repeatability of the system with random positions of the tags. The outcome validates that the proposed antenna, along with the developed methodology, can be used in warehouses for monitoring the positions of the products as well as in the peer-to-peer surveillance of products if they have any unauthorized movements from the shelves.

摘要： This letter presents a new methodology for designing chipless RFID tags with high code density and robustness and validates its effectiveness. The method includes four main steps: designing a resonant unit without a second harmonic, constructing the entire tag structure using a nested loop strategy, adjusting the distribution of resonance points to achieve uniform spacing, and further optimizing the tag performance. Using this method, we designed a chipless tag with a code density of up to 180.45 bits/λ02 and a working frequency range of 7.9-13.6GHz. Experimental results demonstrate that the designed tag has a coefficient of variation of the resonance frequency point interval of 12.97% and a small variation in the resonance peak amplitude of 4.36dB. These results confirm the effectiveness of the proposed method in achieving high code density and robustness in chipless RFID tags. © 2002-2011 IEEE.
